Application led September 24, 1909. Serial Nro. 519,420.

To all whom 'it may concern Be it known that I, ROBERT L. CooNEY, a citizen ot the United States, residing at Atl-anta, in .the county of Fulton and State ot Georgia, have invented new and useful Improvements in Stationary Fire-Extinguisher Systems, of which the following is f u specification.

This invention relates to improvements in stationary fire extinguisher systems.

The primary object of the invention. is the combination with a stationary fire extinguisher system of a novel hose cabinet attachment. In this respect the invention contemplates an arrangement especially applicable .to the stationary systems of large otiice buildings, hotels, apartments, etc., whereby the opening of the door of thecabinet or the manual withdrawal of the hose from the cabinet., produces the operation of The arrangement is to be pre ferred to ordinary distributing valvessince its operating parts are concealed, may be locked it desired against unauthorized access, are not subject to accidental operation or to the experiments of meddlers or loafers and provide (in the case of pressure controlled systems) double assurance of the operat-ion of the system, since if the pneumatic impulse incident to the insufiicient to produce the operation of the sysadditional means operable, subsequently to the opening of the distributing valve is employed to produce the [operation of the system in a certain manner.

A further object of the invention is to provide asan adjunct of a system of the general type which forms the subject of my co-pending application Serial Number 540,661, a means or device located at the vent of the distributing pipe for creating a suction influence in the latter which influence is transmitted by the distributing pipe to the plunger which controls the discharging operation of the acid bottle and causes an operative movement of said plunger. f

A `preferred and advantageous embodiment of the inventionis shown by way o example in the accompanying drawings.

In the said drawings: Figure 1 is a sectional view showing the application of the arrangement to a System of pressure control. Fie. 2 a perspective view of the cabinet amil the adjunct-ive Amechanism inclos'ed -flows to the distribi'iting system..

therein. Fig. 3 is al horizontal sectional view of the cabinet.

Similar characters of reference designate corresponding parts throughout the several views.

The invention is shown, by way of example, as carried out in connection with the system or apparatus which forms the sub- 'ect of my (zo-pending application Serial Tumber 540,661 and which therefore need be described only in a general way. Said system or apparatus ,includes a tank, as 1,

which is connected to a distributing pipe 2 by a secondary shell, as 3, to which a barrel, as 4, is connected. rlhe barrel e projects into thc tank 1 and therein is provided with a depending pipe, as 5, through which the fireextinguishing agent lliflithin the barrel l is arod, as (i, which projects inwardly into the tank through an enlarged opening in the end or" the ^arrel. rlf'he rod 6 is provided with a head 8 which works in lthe shell 3 and normally closes the end ot the barrel 4 and also with a head 9, within the tank 1, and-which, when the system is working, closes the aforesaid enlarged opeinng.` The systern shown is of the 'chemical mixing type and includes an `1nvertibl.` .acid bott-le, as 10, which, upon inversion, discharges its contents into a body of alkaline solution contained in a tank. The generation of a gas fatal to combustion th'enfensi1es in,I the well. known manner.

The bottle l() is operatively connectedto the rod 6 by a chain, as 11. In this arrangement the tank and the system are connected by a .branch pipe, as 14, which has an apertured diaphragm oiits equivalent, as

'15.' By virtue of the construct-ion detailed,

pressureintroduced into the distributing pipe from any suitable source (not shown) will enter the shell 3 and likewise, owing yto the provision of pipe 14, will also enter the tank 1 to an equal degree. The apertured vdiaphragm 15 maintains the pressure in the tank normally equal to that in the distributing pipe and in the shell 3, thus compensating for slight leakages from any cause whatsoever, but, should a distributing valve be opened, the pressure in the pipe 2 and in the shell 3 will be vsuddenly and materially reduced. T h'e apertured web 15 will not compensate for this sudden and material reduction of pressure, and, there fore, the pressure in vthe tank 1 retains most ico lio

. Soli fdrce and,llpas'sing through the aforesaid large opening in the, barrel 4, acts on the head 8, forcing the'same and therewith v the 'rod outwardly.v As a consequence oi this operation .the acid bottle is inverted, and generation is set up. y

- The foregoing system is to be considered merely as exemplary of oneapplication of the invention. other types oi" lsystems and constructions maykbe employed within` the purview of' the invention. y y

The construction whichv is exemplary of the present invention includes a cabinet. as V 16, which may be, attached to the' wall or other suitable support and which incloses a line of iexiblehose, as 17, and a distributing valve, as 18, the. latter'being provided at the end of a branch ypipe 19 which is joined to the pipe 2 and projects through a wall of the cabinet 1G. 'The valve 18 has a couplingwhich provides' forA the operative connection with the valve of one end or" the hose' line 17. 'ljhe hose at its other end has the usual- 5 nozzle 2O which, in the present instance, is

.- inserted with the cylinder, prevents the compression of air in the distribution pipe lbut provides for the creation of ai suction iniuence inthe distributing pipe' when the nozzle is withdrawn explained.

"lhe valve 18 is operated by ymeans of an as will bey hereinafter farm,y as 24, which is secured tothe stem of the valve and,v in the closed position of the valve is'dispo'sed parallel to the ron't andv 'rearjv/ails of the cabinet. The iront wall,

designated by they numeral and constitutl y ing' a door, is hinged to one of the side walls of the cabinet and at its'free side may be provided with a iinob or hand grip 26 havming a latch arm 27. lf desired, any approved loch may be substituted for this rangement. rEhe door 25 is also provi-ded on its inner faceA with an inwardly project ing pivoted catch, as 28,*which is ymn'mally heid in a horizontal position, being capable .of upward vmovement but incapable of downward movement from said position. vJl/'henthe door isclosed the bill of the catch 28automatically engages over the arm 24 and it follows thatyvhen the door is opened the arm 24, by virtue of the engagement `oithe catch 28 therewith, will be swung' outwardly as indicated in dotted lines 1n Fig.

and they valve'ld'thereby opened. When It is not obligatory and.

Lovaoia i this action has taken place, if the system. herein described is employed and has a nor-4 mal charge of air or gesunder pressure, such air or gasflowing through the hose line 17 will expand in the cylinder 22 and will thereby act against the piston head 21 yand force the same and therewith the nozzle 0 from said cylinder.v The expansion of the air or gas incident to the opening of the valve 18 will also produce the unbalancing of the pressure forces and the consequent operation of the system in the manner.A explained. t'

In, case the system is dormant, e. withure to originally charge thasaine or on account ot leakage, the opening` of' the valve 18 is without e'ect in so far as producing the operation of the system isv concerned. "In such a case the operationrof the system is produced 'by thefmanual withdrawal of the nozzle 2O and piston head 21 from the cyl inder 22,"such withdrawal causing a suction influence in the hose line, the pipe 2 and the 'barrel 3 and this positively induced suction influence causing the operative movement of the head 8 and therewith of the rod (i, as a its operation in the manner previously de scribed. f
